Description

Technical Field

[0001] The invention relates to the field of blast furnace safety production equipment, and in particular to a safety emergency shower device for blast furnace smelting. Background Art

[0002] Blast furnace smelting is a continuous production process, and the whole process is completed in the process of the charge from top to bottom and the coal gas from bottom to top. The charge is loaded into the furnace from the top of the furnace in a certain batch, and hot air heated to 1000-1300℃ by the hot blast furnace is blown in from the tuyere. The coke in the charge burns in front of the tuyere, producing high temperature and reducing gas, which heats the slowly descending charge in the process of rising in the furnace, and reduces the oxide in the iron ore to metallic iron. In the process of iron-making blast furnace production, molten liquid slag flows out from the iron outlet, molten iron enters the molten iron tank through the iron ditch, and liquid slag enters the slag treatment system through the slag ditch. Personnel are easily burned and their skin scalded due to splashing of liquid slag or accidental contact with high-temperature slag. In addition, burns are very likely to occur when replacing the air supply device of the blast furnace, cleaning the red coke in front of the tuyere, or accidentally contacting high-temperature flames and objects. If burns and scalds are not treated in time, the area and depth of the wound will increase, so clean and constant temperature water should be used for showering as soon as possible to carry out emergency spray cooling treatment for burns and scalds, so as to reduce the damage to the body caused by burns and skin scalds as soon as possible.

[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] like Figure 1-2As shown, the utility model is a safety emergency shower device for blast furnace smelting, comprising a U-shaped tube 1, on the pipe at the water inlet end of the U-shaped tube 1, an electromagnetic control valve 2, an electronic thermostat 7, a cooler 8, a heater 9 and a water purifier 10 are arranged in sequence from near to far, the electronic thermostat 7 is used to detect and control the water temperature, and its set temperature is constant at 15°C, the cooler 8 is used to cool the water source in summer, the heater 9 is used to heat the water source in winter, and the water purifier 10 is used to purify the water source and eliminate microorganisms, so that the water contacting the burns is clean water. The water outlet end of the U-shaped tube 1 is welded and connected to a strip-shaped and horizontally centered shower head 6, the height of the shower head 6 is 1.8m, which is higher than the human head, and the vertical part of the U-shaped tube 1 close to the shower head 6 is provided with a sensing probe 11, the height of the sensing probe 11 is 1.0m, which is close to the waist height of the human body. The bottom of the U-shaped tube 1 is connected to one end of the drain pipe 4, and the other end of the drain pipe 4 extends into the water collecting bucket 5. The drain pipe 4 is provided with a drain valve 3. The drain pipe 4 is located below the lowest point of the U-shaped tube 1, and the water collecting bucket 5 is lower than the drain pipe 4. It is used to drain the safety emergency shower device in winter, and the accumulated water in the drain pipe 4 flows into the water collecting bucket 5 as much as possible. The electronic thermostat 7 and the induction probe 11 are respectively electrically connected to the signal input end of the PLC programmable controller, and the signal output end of the PLC programmable controller is respectively electrically connected to the electromagnetic control valve 2, the drain valve 3, the cooler 8, the heater 9 and the water purifier 10.
